Two objects, both mass m, are going opposite, parallel
directions at a speed v. They simultaneously hit and stick to a rod
of length L and mass M. The rod is positioned perpendicular to the
paths of the two objects.
a) What happens to the total momentum and angular momentum in
the collision? What are the initial and final values?
b) Is any mechanical energy lost in the collision? If not, why
not? If so, how much?

One object is moving and one object is at rest. The two objects then collide in a dimensional, completely inelastic collision. So the two objects stick together after the collision and move off with a common velocity. Momentum of the two-object system is conserved. The masses of the two objects are 5.00 kg and 8.50 kg, respectively. The speed of the moving object masses 5.00 kg before the collision is 22.5 m/sec. Find the final speed of the two-object system...
